This LS7 engine family utilizes a Mast Motorsports engineered camshaft that is custom ground on a Mast Motorsports 3 bolt cam core. The 427 Black Label’s foundation is a fully machined aluminum block with a forged Callies rotating assembly with CP Carrillo pistons that is topped off with Mast Motorsports Black Label LS7 305cc cylinder heads. ARP fasteners are used throughout and Mast Motorsports Black Label pushrods ride on GMMP High RPM hydraulic roller lifters. This hand built LS7 based engine utilizes a camshaft that has a strong lope that creates great mid and high RPM power for the customer that will be aggressively racing their vehicle, but still wants great street manners for a daily driver.
